22 Small Nuclear Power Reactors
IAEA defines “small” as under 300 MWe Renewed interest in small reactors partly in response to high capital cost of large power reactors Lends to modular construction and incremental additions in capacity Assessment by IAEA in 2009 concluded that there could be small modular reactors (SMRs) in operation by 2030 Other countries are likely to build and operate SMRs ahead of the U.S. Russia will commission a floating nuclear plan (35 MWe PWR) in 2011 FY 2011 President’s Budget Request included $39M for SMR development DOE exploring public-private partnership to pursue NRC design certification for 1 to 2 SMRs employing LWR technologies Commercial deployment of SMRs expected in the U.S. around 2020 Restricted Proprietary Information

24 Application of Export Controls Definition of Key Terms
Source Materials: Material in any physical or chemical form or ores that contain by weight 0.05 percent or more of uranium or thorium (or in combination). Depleted uranium (left over from uranium enrichment) is considered a source material Source Material Licensing: 10 CFR Part 40 Special Nuclear Material (SNM): Plutonium, Uranium-233, Uranium enriched in the isotopes U-233 or U-235. Pu and U-233 do not occur naturally SNM Licensing: 10 CFR Part 70 By Product Material: Non-SNM material that is radioactive and produced either by fission process or by using SNM. Examples are Tritium (H-3), Carbon-14, Flourine-18, Cobalt-57, Krypton-87, Radium-226 By Product Licensing: 10 CFR Part 30 Restricted Proprietary Information

25 Nuclear Facilities and Equipment Under NRC Export Licensing Authority
Major equipment used in nuclear reactors: Reactor pressure vessel On-line fuel charging and discharging machines Control rod system and drive mechanisms Reactor primary coolant pump Zirconium tubes Reactor internals (NSSS) Major equipment (especially designed or critically important) for following plants: Separation and enrichment of isotopes of uranium and lithium Fabrication of nuclear reactor fuel assemblies Reprocessing of irradiated nuclear reactor fuel Production of heavy water Conversion of uranium and plutonium Production of SNM using accelerator driven systems above 5MWt Restricted Proprietary Information

26 Nuclear Material Under NRC Export Licensing Material
SNM* Source Material* Byproduct Material* Deuterium (heavy water) Nuclear grade graphite Full details in 10 CFR Part 110, including latest updates * Requires NRC Import License Restricted Proprietary Information

27 Department of Commerce-Bureau of Industry & Security (BIS)
Export licenses cover “Dual Use” items BIS export licenses may be required depending on the nature of the item, the country of destination and specific “end-use” Export licenses may apply to major equipment and technology in the Balance of Plant (BoP) High pressure turbines Condensate pumps, valves and motors Main generators and back-up generators Transformers Fire detection and suppression systems I&C used in BoP Radiation detection Telecommunications Tools and maintenance Additional guidance from BIS: Restricted Proprietary Information
